As a Summer of Code student, you will be given access to the monotone
repository, so you will be able to commit your changes (with
supervision from your mentor, at least at first) directly to the Pidin
monotone codebase. Depending on your project's impact, you may be
working on a branch while this happens, rather than on trunk; Sadrul
and the other developers will help you decide which is most
appropriate. (It looks like your functionality is core enough that
you will probably want to use a branch, and merge your changes over to
trunk as they become stable.)

Perhaps UsingPidginMonotone should be clarified, if I understand your
question. With monotone, anyone can commit to their local repository,
and there is nothing we can do to change that. In fact, we *like*
that! However, in order to be able to push those changes to the
monotone repository on pidgin.im, you must have an approved key.
Changes committed by non-developers can be shared with whomever those
developers like, but they cannot be uploaded to pidgin.im to be
part of the official Pidgin tree without the assistance of a core
developer with write access to that repository.

Quilt is overkill for the sort of patch splitting that one *normally*
needs to do on a project like Gaim. There are certainly cases where
it may be beneficial, but we actually believe that a DVCS like
Monotone will reduce those cases, due to the fact that branches and
"private" commits become so much cheaper and easier, or even possible.
The monotone crowd has discussed quilt functionality in the past, and
I'm not sure what the results were -- you can check the mailing list
archives and wiki at monotone.ca for more information.
(Patch stacks become a much bigger deal for, say, the kernel, where
you have external developers making large changes, or internal
developers making large changes which go through a long review before
release, requiring continual integration with various versions for
compatability and bug testing. With Gaim, these things are not a real
problem -- external developers very rarely submit large patches with
divisible requirements, and more earth-shaking changes are free to be
integrated into the main tree.)
The laws that forbid the carrying of arms are laws [that have no remedy
for evils]. They disarm only those who are neither inclined nor
determined to commit crimes.
